Regex (Regular Expression)

Regular Expression

1. What's it?

From the 2.3.0 version, Proxyman supports Wildcard and Regex (Match a whole word) when you define matching rules for all available tools:

• Map Local

• Map Remote

• Block & Allow List

• Breakpoints

• Protocol Buffers (Protobuf)

• Reverse Proxy

• Network Throttling

• ...

It's a handy tool to help you exactly define which requests should trigger the tool.

Match a request by Wildcard or Regex

2. Test your URL (New feature 🎉)

From Proxyman v4.8.0, you can quickly test your Rule (Wildcard / Regex).

• You can quickly test & play around with your Wildcard/Regex

• Save time: You don't need to go back and forth to check your URL.

• Less error-prone.

How to use it?

1. Open any debugging tools (Breakpoint, Map Local, ...) -> Create a new rule

2. Click on the "Test your Rule" underline button -> New Window is opened.

3. Add your Rule and URLs you'd like to check

• ✅ Matched: Your URL is matched with your rule.

• ⚠️ Not Matched: Your URL doesn't match your rule. You might rewrite your wildcard/Regex rule.

3. Wildcard

Proxyman supports simple Wildcard characters, which include * and ?

Wildcard	Purpose
*	The asterisk in a wildcard matches any character zero or more times.
?	A question mark matches a single character once.

For instance:

• http://proxyman.io/v1/*

• https://myserver.com/v?/*

4. Regex

Proxyman also supports Regex.

• Make sure your regex is matching a whole URL.

• Partial Matching is considered as not matching.

• Make sure you escape characters properly: Splash (/), full-stop (.), etc.

For instance:

Regex	Matched URL Examples
https:\/\/proxyman\.io.*	https://proxyman.io https://proxyman.io/v1/data?id=123 https://proxyman.io/pricing
^(http|https):\/\/www\.google\.com.*	http://www.google.com http://www.google.com/user?id=proxyman https://www.google.com
^(http|https)?:\/\/www\.google\.com\/v[0-9]?\/build\?query=proxyman	http://www.google.com/v1/build?query=proxyman www.google.com/v2/build?query=proxyman

You can use https://regex101.com/ to verify your Regex that matches the whole text.

Make sure your Regex matches whole words

Please check the Regex Metacharacters, Operator and Flag from Apple Developer Documents to know which one is supported.

Check https://regex101.com and make sure your Regex is full-matching with the given URL

• Select Regex when creating rules

With regular expressions the meaning of ? and * is different from that of wildcards. The equivalent of wildcard ? is the regex . and the equivalent of wildcard * is the regex .*
